What is a Raw material
Raw material specification
Why is it important to conduct raw material specification?
What is a Raw material
Product ingredients e.g. fruit and veg
Processing materials e.g. steam and water
Food additives e.g. emulsifiers, starches, colours
Packaging materials e.g. bottles and cans
Raw material specification (Know a food example - AT1 Jam)
Descriptions/Specifications of Raw Material
Test for each specified characteristic
Sampling method for the material
Action - accept or reject based on test results/ start procedures to control the problem to prevent further deterioration
There is no value in specifying a characteristic unless it can be tested

Advantages of using additives to food
VC 4 S
Advantages of using additives to food
Can sense very shelf-safe nutrients Improved: - Consistency of food - Sensory properties - texture, flavour appearance, aroma - Variety of food available - Shelf life thus reduces waste - Safe food - Specific nutrients fortification

R = reactions adverse A = affect behaviour N = not natural (mostly)
FM8
Levels of Food Production - Small Raw Materials Quality Control (QC) Equipment Staff Output Distribution
Raw Materials - 2-day supply Quality control (QC): - Little/no technical equipment - Q.C done by visual inspection - No lab and less documentation
Equipment:
- Domestic style/size hand-held mechanical appliances
- Hand-held mechanical appliances.
Staff – multi-skilling of fewer people
Output:
- Small product range produced over 1 week novelty/niche products
- Novelty/niche products
- Less unit operations and basic packaging
Distribution - Small delivery vans
FM9
Levels of Food Production - Large Raw Materials Quality Control (QC) Equipment Staff Output Distribution
Raw Material - Large stockpile as warehoused under controlled temp. conditions
Quality Control (QC)
- Q.C managers
- Food technologists & lab technicians
- Comp. controlled systems.
- H.A.C.C.P control/ documentation
Equipment:
- Hi-tech, continuous flow, computer/robotic systems.
Industrial cleaning/sanitization. Stainless Steel.
Staff - Extensive & high qualified to lesser skilled range
Output:
- Large production in batches
- 24/7 incl. 1-2 processing stages and hi-tech packaging.
- Fast
Distribution - Own logistics system and truck fleet w/ cold chain.
FM10
Levels of Food Production - Manual
Characteristics
Characteristics
- Person physical handles the raw materials or food product.
- Most commonly used in small scale production.
Minimal mechanical equipment is used e.g. food processor, electric mixers
FM11
Levels of Food Production - Manual
Pros Cons
Pros
- Hand-made’
- Sense of control
- More skilled workers - - Flexibility in menu/food items
- Lower supply costs.
- Quality control determined by the individual
Cons
- Labour-intensive.
- Safety risk to people and of food contamination.
- Smaller batches.
- Inconsistency.
- More susceptible to human error.
- Large ongoing staff training cost.
- Time consuming and costly to produce reports.
- Lack of security.
FM12
Levels of Food Production - Automated/Computerised Characteristics
Automated
- Uses specially designed machines to control processing on a large scale.Uses repetitive actions, pre-determined conditions to ensure product standardisation.
- Fully automated production may control all processes - from mixing to packaging and labelling.
e. g. Tunnel dryers, centrifuge, blast chillers/freezers.
Computerised known as CAM (Computer-aided Manufacturing).
- Large scale production systems involving the monitoring and controlling of production using sensors and timing systems.
- Sensors note temperature, detect changes or foreign objects such as metals.
- Changes are sent through microprocessor which analyses the data and makes changes if necessary, such as increasing temperature.
FM13
Levels of Food Production - Automated/Computerised
Pros Cons
Pros
- Reduced labour and need for employees
- Long hours or 24/7 production
- Higher output and faster process
- Conserving of human energy
- Less wastage of materials
- More consistent and standardised production levels
- Automatic shutdowns can be installed to ensure safety argins are maintained
- Generally, a wider target market and distribution area
Cons - Requires specialist technicians Impersonal; not 'hand-made' - Less specialisation Costly - Requires constant servicing of machinery - Possibility of malfunctioning
FM14
Characteristics of Processing Equipment (S.H.E.D):
S: Safe - machines are to be fitted with safeguards to prevent injury. Equipment in made of stainless steel, which is strong, scratch resistant and impervious. Food technologists/trained operators are responsible for the operations and equipment.
H: Hygienic - an efficient cleaning process called ‘Cleaning in Place’ (CIP) - a mixture of chemicals, heat and water to clean and sanitize machinery, fittings and pipes. Equipment needs to be easy to clean.
E: Effective and:
D: Durable - reliable equipment as breakdowns can be costly as production ceases. Operating 24/7 therefore needs to be energy efficient.
Be able to compare and contrast commercial equipment with domestic e.g. combi oven with domestic oven
FM15
Give examples of the processes in each unit operation and what food it is used in food manufacturing.
Separation
Physical- bran from flour.
- Fiitration -cheese curd from water

Flow Process Charts
Definition
Symbols and meaning
Define - A flow process chart is a graphic representation of production processes involved in the manufacture of a specific product.
Operation - Operations are when raw materials are deliberately changed physically, chemically or prepared for another operation e.g. via heating.
Inspection - The product is compared to a standard by checking, sampling, examining, and measuring E.g. recording pasteurization temperature.
Transportation - Move materials from one place to another E.g. forklifting apple pallets.
Delay - Conditions don’t allow next step of process to occur, or next
D production step that doesn’t happen immediately E.g. shortcomings in process design, wait for yeast react.
Storage - The product is kept under controlled conditions before selling E.g. canned beans on shelf.
Know an example - e.g. jam
